API Standard 5 7/8 Inch IADC 637 Tricone Roller Bit for Construction Drilling
Professional API steel tooth TCI tricone clay bit water well drill bit with elastomer sealed bearing system.
The roller bit is a widely used drilling tool that features alternating cutting teeth contact with the well bottom, resulting in small rock breaking torque and high specific pressure for efficient penetration into various formations.
- Oil-storage sealed sliding or rolling bearing system with jet-type three-cone design
- Optimized tooth arrangement with different tooth shapes and heights for various rock formations
- Enhanced diameter protection performance with anti-friction alloy bearing system
- Silver-plated, precision processed components for anti-bite and high load-bearing capacity
- High-toughness carbide teeth with optimized design parameters
- Widely used in oil, gas field exploitation, and geological drilling applications
| IADC WOB (KN/mm) | RPM (r/min) | Applicable Formations |
|---|---|---|
| 417/437/447/415/435 0.35~0.9 |
150~70 | Very soft formations with low compressive strength and high drillability |
| 517/527/515 0.35~1.0 |
140~60 | Soft formations with low compressive strength and high drillability |
| 537/547/535 0.45~1.0 |
120~50 | Soft to medium formations with low compressive strength |
| 617/615 0.45~1.1 |
90~50 | Medium hard formation with high compress strength |
| 637/635 0.5~1.2 |
80~40 | Hard formations with high compressive strength |
Note: The upper limits of WOB and RPM in the table should not be used simultaneously.
- Alternating cutting teeth contact reduces rock breaking torque
- Small contact area with well bottom creates high specific pressure
- Easy penetration into various geological formations
- Extended working edge length reduces wear
- Adaptable to formations ranging from soft to hard
